These triple chocolate cookies combine a fudgy brownie mix base with semi-sweet and white chocolate chips and toasted walnuts for a chewy, rich, and crunchy treat that’s quick and easy to make.

Ingredients

Scale
  • 1 box brownie mix (about 18.3 oz / 520 g)
  • 1/3 cup vegetable oil (80 ml)
  • 2 large eggs, room temperature
  • 3/4 cup semi-sweet chocolate chips (135 g)
  • 1/2 cup white chocolate chips (90 g)
  • 1 cup chopped walnuts, toasted (120 g)
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt

Instructions

  1. Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat.
  2. Toast the walnuts: Place chopped walnuts in a dry skillet over medium heat. Stir frequently for about 4–5 minutes until lightly browned and fragrant. Set aside to cool.
  3. In a large bowl, combine the brownie mix, vegetable oil, eggs, vanilla extract, and salt. Mix until smooth and well combined, about 1 to 2 minutes using a hand mixer or sturdy spoon.
  4. Fold in the semi-sweet chocolate chips, white chocolate chips, and toasted walnuts gently until evenly distributed.
  5. Using a tablespoon or cookie scoop, drop dollops of dough about 2 inches apart on the prepared baking sheet.
  6. Bake for 12 to 14 minutes until edges are set but centers look slightly soft.
  7. Cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.

Notes

Toast walnuts in a dry skillet for about 5 minutes until fragrant to enhance flavor. For dairy-free, use vegan chocolate chips and flax eggs. Chill dough 15 minutes before baking if cookies spread too much. Avoid overmixing after adding chips and nuts to keep cookies tender. Add mini chocolate chips on top before baking for extra gooeyness.
